CWDM Mux/Demux Module are based on thin film filter technology. CWDM technology provides the flexibility to increase capacity of existing fiber infrastructure by enabling multiple channels (wavelengths) over the same fiber cabling. Each channel carries data independently from each other, allowing network designers to transport different data rates and protocols for different customers or applications.
CWDM can solve the shortage of fiber and transparent transmission of business, and reduce the cost of network building. With low-cost low power consumption and small compact, it is widely used in metro aggregation and access layer to do transmission on a short time.
Our CWDM Mux/Demux products provide up to 16-channel or even 18-channel Multiplexing on a single fiber. Standard CWDM Mux/Demux package type include: ABS box package, LGX package and 19" 1U rack-mount.
